Rock collision bugfix

It's funny because [Dev]Rawrster wrote in the feedback of the contest that the map is attack oriented. I agree that defense dont spread too much but if you conquer one of the three strong points the defense will have bad moments. I checked statistics and ...... defense wins a bit more than attack. It's a big question......Anyway tks for the feedback.

I think that this map would be more balanced if there was a bomb a little closer to the assault side (maybe where that bear walkway or whatever it's called is). As it is, the map is extremely defense oriented because they don't need to spread out too much to cover both sites.

Updated/bugfix

To avoid server mismatch errors during the Map Feedback Event, please do not update this map on the Workshop again until December 21. If you update the file and the server has a mismatch error, this map will have to be removed from the Feedback Event's servers.

Bugfix update.

Tks to DeltaThunder for his artic packet
